首先我的博客记理论知识很少，大家对spring boot、spring cloud 、分布式 、微服务什么的一点概念都没有的还请先去百度看看理论，知道了是做什么用的，然后再写下demo ,这样学起来才没有那么迷糊！
我一般写下的demo都是我踩了很多坑，或者说很多人在其他地方写下的demo搬过来根本运行不起来，然后我经过处理和查询，整理了一下！
方便我以后再回来查找，也方便有些小伙伴入门的demo!
我就简略的介绍一个这个demo;就是spring cloud 中的一个注册服务器 、注册管理中心 会自动监控！
这个demo是我从官网上面找下来的，然后注释了一些用不上的代码和配置！
我这里采用的idea编辑器！
第一步：我们建立一个spring boot项目
如下图：一直next.......最后Finish
第二步：修改maven的pom文件，文件已经给你们整理好了，如下：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 "> <modelVersion>4.0.0</modelVersion><!--描述这个POM文件是遵从哪个版本的项目描述符。--> <groupId>com.example</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>demo</name> <description>demo project for Spring Boot</description> <parent><!--父级依赖，继承--> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.2.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <dependencies><!--引入依赖--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <!--声明依赖，如果dependencies中没有声明版本就会来这里面找--> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Finchley.BUILD-SNAPSHOT</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <properties><!--定义的标签属性可以在其他地方读取--> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <start-class>com.example.demo.DemoApplication</start-class> <java.version>1.8</java.version> <!-- <docker.image.prefix>springcloud</docker.image.prefix>--> </properties> <build> <plugins> <!-- <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>0.2.3</version> <configuration> <baseImage>openjdk:8-jre-alpine</baseImage> <imageName>${docker.image.prefix}/${project.artifactId}</imageName> <exposes>8761</exposes> <entryPoint>["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/${project.build.finalName}.jar"]</entryPoint> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin>--> <!-- <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <!– defined in spring-cloud-starter-parent pom (as documentation hint), but needs to be repeated here –> <configuration> <requiresUnpack> <dependency> <groupId>com.netflix.eureka</groupId> <artifactId>eureka-core</artifactId> </dependency> <dependency> <groupId>com.netflix.eureka</groupId> <artifactId>eureka-client</artifactId> </dependency> </requiresUnpack> </configuration> </plugin>--> <!-- <plugin> <groupId>pl.project13.maven</groupId> <artifactId>git-commit-id-plugin</artifactId> <configuration> <failOnNoGitDirectory>false</failOnNoGitDirectory> </configuration> </plugin> <plugin> <!–skip deploy (this is just a test module) –> <artifactId>maven-deploy-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin>--> </plugins> </build> <!-- <!–相当于配置远程仓库–> <repositories> <repository> <id>spring-snapshots</id> <name>Spring Snapshots</name> <url>https://repo.spring.io/libs-snapshot</url> <!–是否自动更新–> <snapshots> <enabled>true</enabled> </snapshots> </repository> <repository> <id>spring-milestones</id> <name>Spring Milestones</name> <url>https://repo.spring.io/libs-milestone</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>spring-releases</id> <name>Spring Releases</name> <url>https://repo.spring.io/libs-release</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> <!–插件仓库–> <pluginRepositories> <pluginRepository> <id>spring-snapshots</id> <name>Spring Snapshots</name> <url>https://repo.spring.io/libs-snapshot-local</url> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> <pluginRepository> <id>spring-milestones</id> <name>Spring Milestones</name> <url>https://repo.spring.io/libs-milestone-local</url> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> </pluginRepositories>--> </project>
